  • Crosman .177-cal. steel breech kit
  • Fits Crosman airgun models 1377,* 1740, 1760 and PC77

The original rear sight that comes with any of these airgun models will no longer fit on the steel breech. If you want a rear sight, the Crosman LPA MIM rear sight is made for this kit (CR-2300-010[PY-A-4385]).

Things I liked:

The steel breech is more rigid than the plastic one, and has more support surface for the barrel.

Things I would have changed:

The undercut on the breech is contoured 2240/1740 tube. The 1377/1322 tube is slightly smaller in diameter. It still tightens down, but the tolerance is kind of sloppy. I wish they would make one specifically for the 1377/1322

What others should know:

The O-Ring on the bolt probe seems to ship dry. Oil it as detailed in the airgun's owners manual to prolong the life of the seal.

Things I liked:

Steel, nice weight and good finish. Secures very nicely and was easy to install after some fiddling even without looking at instructions(do still look at instructions there's no reason not to).

Things I would have changed:

Blue loctite on the bolt handle threads but you can do it yourself quite easy and loctite is always good to have around anyways, it'll just come loose after working the action a few times(or maybe I'm just rough).

What others should know:

This with the stock makes for a very accurate little plinker.

  • elcue from USA asked:

    What adapter do you use to mount a red dot sight on the 1377 with the steel breach. I have bought dovetail to weaver adapters to mount a sight and they do not fit the dovetail. I for some reason I just realized it states in the description. (Does not fit 3/8", 11mm, Weaver or Picatinny dovetails/bases) Duhh on me! What is used to mount a red dot or scope if desired?
